Usage with Claude

• on macOS claude_desktop_config.json is located in ~/Library/Application Support/Claude/.

• on Windows You need to create a new claude_desktop_config.json under %APPDATA%\Claude.

• Homebrew on macOS

Homebrew installs age-mcp-server into $PATH.

{
  "mcpServers": {
    "age-manager": {
      "command": "age-mcp-server",
      "args": [
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
      ]
    }
  }
}

• uv / Pyhon venv

On macOS:

{
  "mcpServers": {
    "age-manager": {
      "command": "/Users/your_username/.local/bin/uv",
      "args": [
        "--directory",
        "/path/to/your_project",
        "run",
        "age-mcp-server",
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
      ]
    }
  }
}

On Windows:

{
  "mcpServers": {
    "age-manager": {
      "command": "C:\\Users\\USER\\.local\\bin\\uv.exe",
      "args": [
        "--directory",
        "C:\\path\\to\\your_project",
        "run",
        "age-mcp-server",
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
      ]
    }
  }
}

If you need to hide the password or to use Entra ID, you can set --pg-con-str as follows.

{
  "mcpServers": {
    "age-manager": {
        ...
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username",
        ...
      ]
    }
  }
}

And, you need to set PGPASSWORD env variable, or to install Azure CLI and sign into Azure with your Azure account.

After saving claude_desktop_config.json, start Claude Desktop Client.

Usage with Visual Studio Code

After installing, [Preferences]->[Settings] and input mcp to [Search settings].

Edit the settings.json as followings:

{
    "mcp": {
        "inputs": [],
        "servers": {
            "age-manager": {
            "command": "/Users/your_user_name/.local/bin/uv",
            "args": [
                "--directory",
                "/path/to/your_project",
                "run",
                "age-mcp-server",
                "--pg-con-str",
                "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
                "--debug"
            ]
            }
        }
    }
}

And then, you'll see start to start the AGE MCP Server.

Switch the Chat window to agent mode.

Now, you can play with your graph data via Visual Studio Code!

Write Operations

AGE-MCP-Server prohibits write operations by default for safety. If you want to enable write operations, you can use the --allow-write flag.

{
  "mcpServers": {
    "age-manager": {
      "command": "age-mcp-server",
      "args": [
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
        "--allow-write"
      ]
    }
  }
}
